Simplified Calculation of pulse transformers

I want to talk about the calculation of the pulse transformers, in the network it is described many techniques, but use some incomprehensible coefficients, those numbers where they come from? No one clearly describes, if I do not understand something or if I do not spegano clearly I will never be able to replicate what they learned and if necessary adapt it to my needs.

Let's start with the fact that we want to achieve a certain device, it needs a power supply, for example, equal to 250 watt, then you must select the magnetic circuit capable of delivering this power.

For this, there is a real formula for estimating the overall input power of a magnetic element:

kf is the form of voltage or current: for breast = 1,11 for the rectangle = 1.

KLC – Factor of the geometric cross section of the magnetic filler material feromagnetica GLC = 0.6 – 0,95, and it is available in reference books on magnetic element.

Amilcare I must say that you are always in the field despite the commitments ,but the passion is beyond praise limit , go on
I'm always struggling my Power 4Kw x2 , I decided to do it straight , I'm testing .
